Here above you can see how the shipyard made the structural part of the canting keel system.1) The JIC is placed between the two main bulheads and glued on the hull. 2) JIC is removed and longitudinal plates and floor are placed between the bulkheads3) The canting keel system (rams, bearings and accessories) are placed on board

The canting keel feature dramatically im-proves the righting moment of the boat al-lowing more power for race yachts or more comfortable sailing for cruisers.

Cariboni’s experience in canting keel sys-tems dates back to 1996, when Junoplano was designed; this single ram system, with a +/- 55° canting angle, has been a mile-stone in sail history.

Cariboni designs and supplies canting keel system with:- A single double acting cylinder- Two double acting cylinders- With integrated aluminium or stainless steel frame- JIC system to build the keel bulkheads- Aluminium, stainless steel and titanium rams

In every kind of canting keel, the system is watertight: the central part (where the keel head moves) is flooded, but the cylinders work in a dry area guarantee by special custom rubbers, placed between the rams and the longitudinal plates.

The keel frame allows to have a self-contained canting structure easily to be placed inside the boat. The shipyard has just to pick-up the structure and fix it between the two main bulkheads. The loads transmitted to the boat struc-tures are exactly the same loads of a standard fixed keel.These kind of systems are installed on several Wally boats and on the 60’ race-cruisers “Junoplano”, “Kratos” and “Anyway”. In the image you can see the canting keel system of the 105’ Wally “Kauris III” designed by German Frers.

In order to reduce the overall weight of the canting keel, we developed an integrated system which doesn’t need a frame as all the parts are placed straight on the boat bulk-heads. A JIC structure is supplied to the shipyard to place the bulkheads correctly alligned and drilled inside the boat.

These canting keel mechanisms without frame are installed on most of the racers boats.

CANTING KEEL SYSTEM

THE BIGGEST CANTING KEEL IN THE WORLD…

...AND THE FASTEST

140’ MARI-CHA IV is composed by a double acting cylinder with a bore of 380mm and a stroke of 1280mm (358 tons working load).

The particular shape of the boat bulkheads needs a special asymmetrical bearing to be machined.

Cariboni cares a lot about reliability of its system.That is proved by the long sailed before the first service, made after 25000NM.

Only 6.5 seconds from -55° to +55°! This is the outstanding performance of the Cariboni’s cant-ing keel system developed for the 90’ “Genuine Risk”.

The keel control is made by two double acting cylinders feed by PTO diesel engine pumps, with an extraordinary 55° canting keel angle. The PLC system controls the performance of the boat in order to achieve performance, reliability and easy handling of the boat even with this huge amount of power. ACC manual control and deck equipment complete the hydrau-lic system of this milestone boat.

Genuine risk

Our canting keel systems are not a feature only for mega yachts: we developed easy and reliable system also for small boat as Melges 40 race yacht.

Dimensions change but philosophy not: the highest per-formance with the best reliability of the system. Also this compact system has all the Cariboni’s know-how on canting keel system: top materials (high strength aluminium alloy, stainless steel, bronzal bearings) and carefully design are the keys word for this new project.

Melges 40 canting keel main specifications:

- Bulb weight: 1500 Kg- Fin length: 2300mm- Canting angle: ± 45°- Keel ram dimensions: 90mm bore, 505mm stroke made

of aluminium alloy with self-alignment bearings and lin-ear sensor. Working pressure: 280 bar.

The package is complete with our hydraulic system. The main manifold has proportional valve for highest reliability and performance of the system and the electrical and man-ual by-pass for free swing of the fin. A compact PLC elec-tronic board manages the hydraulic system and is linked to a deck electronic gauge for a real-time keel position status. The linear sensor fitted inside the ram is used to have an automatic tacking and canting keel movement.

Built by Knierim Yacthbau in Germany, VARUNA VI is the latest generation racer designed by Ker Design with cant-ing keel and daggerboards.

Cariboni has a long experience in the IMOCA 60 canting keel systems. Since the first FILA in 1997 Cariboni has im-proved the canting technology year after year.

During 2008 - 2009 we supplied six teams with six different keel systems. In 2010 Cariboni has supplied three other teams.Last but not least in 2013: Spirit of Hungary - Nàndor Fa
